• Universal Surface Compatibility: Mounts securely on flat, round, and irregular surfaces including pipe
• Heat Resistant: Built to withstand temperatures up to 176°F (80°C) for reliable performance in demanding shop environments
• Convenient Ground Line Tab: Includes a dedicated tab for easy attachment of the ground cable
• Compact and Lightweight: Weighing only 0.61 lbs with a low-profile design that keeps the work area clear
